VICTOR E. EDWARDS, 0F WORCESTER, MASSACHUSETTS, ASSIGNOR .TO MORGAN CONSTRUCTIfiN COMPANY, OF.WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

Original application filed August 2, 1915,

To all whom it may concern:

Be it known that I, Vro'ron E. EDWARDS, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have in- Vented a new and useful Improvement in gether with the accompanying drawings, is a Specification, the present application being a division of my copending application,

' Serial No. 43,132, filed Au ust 2, 1915.

The present invention re ates to a rolling mill, and has particular reference to an improved form of driving means for the rolls of such a'mill. The invention is shown in connection with a constructionembodying August 1, 1916; but it is to lac/understood that the present invention is applicable to any and all-types of reducing rolls, and is not confined in any sense to employment with the type of rolls herein shown and described. 4

My invention is fully set forth in the following description, reference being had to the accompanying drawings, in which- Figure 1 is a view in side elevation of the mechanism, showing the roll housing in rear end elevation.

Fig. 2 is;a side elevation, partially in vertical section, of the roll housing shown in Fig. 1, and

Fig. 3 is a horizontal sectional view of the roll housing on line 33, Fig. 2.

Similar reference characters refer to similar parts in the different figures.

Referring to the drawings, the base 1 supports at one end a nest gear transmission 2, 1 which is journaled a horizontal shaft 3, rlitatably connected tea driving motor or other prime mover, not shown. The shaft3 is coupled to a second shaft 4, journaled in a pinion housing 5 which is also supported by base 1. The shaft 4 serves for the rotation of one of the rolls of the horizontal stand of rolls contemplated by my invention, being rotatably connected to the driving shaft 6 of said roll in'any well known manner; tne shaft 7 of the other horizontal, roll is similarly connected to a shaft 8,

journaled in the pinion housing 5 and connected by gearing 9 with the shaft 4.

Through the medium-of gearing 10, the rotation of the shaft 3 is communicated to a lower horizontal shaft 11, journaled in the base 1. The said shaft 11, through bevel gearing 12, drives a vertipal shaft 13 journaled in a pinion housing 14. The shaft 13 is coupled, in any well known manner, to .a pinion 15 which serves, in the manner hereinafter described, for the rotation of one of the-rolls of the vertical stand of rollseontemplated by my invention; the other vertical roll is driven from a second pinion 16 journaled in the housing 14, and meshing with pinion 15.

The pinion housing 14 serves for the support of a roll housing 17 which carries both the vertical and the horizontal stands of rolls above referred to. The said roll housing, for convenience of description, may be considered as being divided, roughly, by a transverse wall ,18, into two compartments, one,

.19, containing the stand of vertical rolls 20,

20, and the other, 21, containing the stand of horizontal rolls 22, 22. The compartment 19 is defined by side walls 23, 23, joined together at the top and bottom by transverse upper and lower front walls 24, 25, which have a rectangular opening 26 between them. The compartment 19 thereby presents separated upper and lower substantially inclosed recesses which are designed to contain respectively the upper and lower pairs of bearings 27, 27, and 28, 28 for the necksof the vertical rolls 20, 2

Each pair of bearings, upper and lower, is

capable of sliding movement \vithin'its recess, at right angles to the axes of rolls 20, 20, so that the distance between the axes of the two rolls may be delicately adjusted. To th s end, the opposing inner sides of each pair of bearings are spaced apart, as at 29,

while the outer sides are formed with in-- clinedsurfaces 30,t0' permit the interposition of adjustable wedges 31, between the surfaces 30 and the inner surfaces of the side walls' 23, 23. Said wedges are 'slida-ble through openings in the walls 24 and 25 of the housing, to move the bearings closer together, by means of screws 32, carrying loeking nuts 33 for securing the wedges in any desired position of adjustment. Each wall 24', 25 also carries a screw 34 for moving an I adjustable double'faced wedge 35, which co operates simultaneously with inclined. surfaces 36,36 of the hearings, to force the bearings apart. As shown clearly in"lFig. 3, the bushings 37, 37, for the necks 38, 38,

of. the rolls, are carried'interiorly of said bearings, and are exposed on a portion their outer surfaces J0 the action of said wedges 35, with the result that each wedge 35, in addition to its function in determining the distance between the axes of adjacent rolls, may be forcedinwardly to deformthe soft metal of the bushings and thereby take up any wear between said bushings and the necks 38, 38 of .the rolls.

. The compartment 21 of the housing/1?, containing the pair of horizontal rolls. 22, is defined, roughly, by a pair of. spaced upri ht walls 39, disposed parallel to and at a tance from'the partition 18. In the recesses thus formed; at each sideof the housing,.the bearings 40, 40 and 41, 41 for the necks of rolls 22 are received, said pairs of bearings being adjustable. toward one another by means of screw operated wedges 42, and awa from one another by screw operated wedges 43, the construction and operation of the adjustment devices being identical with yertical rolls.

'40 and 41 of the horizontal rolls.

that described in connection with the bearings 27 and 28and wedges31 and 35 ofthe In the space 26 between the front walls 24, 25 of the housing is supported a fixed re- 'ceiving guide 44 for the metal, said guide.

projecting inwardly into juxtaposition with the pass of the vertical rolls 20, 20. The

partition 18 supports a fixed intermediate guide, not shown, adapted to' convey the metal from the pass of vertical rolls 20 to the pass of horizontal rolls 22. These guides are in axial alinement with each other.and with a-third fixed delivery guide 46, support-- ed by a plate 47 attached to and connecting the rear walls 39 which inclose the bearings The longitudinal or axial adjustment of the rolls, each of which has the usual series of peripheral grooves cooperating to form passes of various sizes, will now bedescribed, it

being understood that the said adjustment iseifectivenot onlyv in bringing a pass into proper alinement with the fixed guides 44 and 46 and the fixed intermediate guide,'but

also in rendering possible the substitution of various'passes, without removal ofthe rolls from their bearings and without disconnecting the driving shafts of said rolls from the shafts of the driving pinions; axial adjustment devices for all the rolls of the two stands of rolls -are identical, .9. de-

scription of the same with respect to the vertic'al rolls will suflic for the horizontal rolls.

' The wallsof housing 17 provide, adjacent the outer end of each roll bearing 27, 28,

and 4hr; plurality of notches 48. Adjusthousing, on the upper end of which a washer zontal roll have'the same'adastment devices Since the inmate ing yokes 49 and 50 disposed at opposite ends of each vertical roll, provide pro ect ng curved cars 51 adapted for reception within said notches to afford 'fulcrums for each yoke. The inner face of each yoke PI'OXldQS raised objections 52 adapted to bear against the outer end of the adjacent bearing. The free end of each upper yoke 49 is slotted for a the passage of a fixed rod 53, carried by the 54 is pressed against the yoke 49 by adjusting nuts 55. The dow'nwardmovement of said nuts rocks the yoke-downwardly, Fig.2,

to carry the upper bearing 27 in'the same direction. Each lower yoke 50- has connected 8" thereto a sliding rod 56, by means of pins 57 which limit relative movement between rod and yoke. The upper end of said rod 56, projecting beyond the housing, carries adjusting nuts 57, by means of which the inwardmovement of the lower bearing 28 is secured. The adjusting devices of the two bearings are thus located conveniently at one end of the roll; andthe inward adjustment of each bearing is made dependent 9s upon the amount by which the adjustment device of the other bearing is loosened. The yokes 49 for the twdbearings of each horias' described above.

Referringto 'Fi 2,"the vertical roll 20 shown therein provides, inthe present instance, fourj-peripheraLgrooves 58, 59, 60 and 61, the roll being so disposed axially as tobring the groove 6Q into approximate 11 alinement withthe guides 44 and 46 and the fixed intermediate guide. In order to secure a delicate adjustment, the two yokes 49. and 50 are moved in or out by the adjusting nuts 55 and 57 In order te bring the groove 61 into the same position as'the groove 60, the Y yokes 49 and 50 are elevated to bring their ears 51 into the notches 48 just above those in which they are shown as located in Fig, 2. In the same manner each of the two other. grooves 58 and 59 ma be rendered available by removing the rol with its bearings 27 and 28, and replacing the same in a reversed. position. It will be clearly understood that each roll of both stands of rolls is longitudi-f nally adjustable in precisely the same manner as above described, in order not only to render the difierent grooves of the same; available to form'the pass, but also to afiord a delicate and accurate alinement of each 712a riving its rotation shaft 1 9 g st square opening for the reception of the square end 62 of a shaft 63, which projects through the yoke 50 and enters the roll 20. The said roll is bored out from end to end, and then squared, so that the square upper end (H of shaft 63 is capable of imparting rotation thereto in all positions of adjustment assumed by the roll. As shown in Fig.

3, the square openings in the roll and in the pinion 15 are slightly larger than the squared ends of the shaft 63, so that suiticient play,.necessary for the slight lateral adjustments accomplished by the Wedges 31 and 35, is afforded. I The shafts 6 and 7have a similar square sliding driving connection opening therein or angular cross section, and a driving means of similar cross section for each roll, engaging the same within said opening, to permit of said longitudinal adjustment without disconnection of the roll therefrom.

2. In a rolling mill, the combination with a pair of reducing rolls each having a series of grooves therein cooperating to form a plurality of passes, of means for adjusting said rolls longitudinally, each roll having an opening of angular cross section extending axially therethrough, and a driving means of similar cross section for each roll eugage able Within said opening from either end thereof, to permit the reversal of a roll, whereby to render all of said passes available for adjustment with said adjusting means.
